bochs for Debian ---------------- In order to use Bochs you need to follow these steps: - Gunzip the sample bochsrc file (in examples/bochsrc.gz) into ~/.bochsrc. - Take a look at ~/.bochsrc and adapt it to your needs. In particular you need to set the "boot:" parameter. The default is to use /dev/cdrom for boot. If you want to start from floppy or hard disk you'll need to change that. - Now invoke bochs from command line or from the menu entry. Upstream documentation ---------------------- It's in the bochs-doc package. Start with index.html. sb16ctrl -------- The sb16ctrl utility can be used to query the emulated SB16 device from WITHIN the emulator. You can compile it with: gcc sb16ctrl.c -o sb16ctrl Add -static if you're not certain that the libc version of the guest and the system where you compile are the same. If your guest OS is debian-based there's a "sb16ctrl-bochs" package you can use. amd64 / x86-64 support ---------------------- You can find an image of Linux, the kernel, for x86-64 in . The site contains an x86-64 toolchain, cpu specification and other resources. Bochs as init ------------- By telling your kernel to use /etc/bochs-init/init.sh as init, you can turn your system into a Bochs-only environment. This may be useful for simulating that you have an i386-based PC on different hardware platforms. It is mainly targeted at embedded systems or some such. If your kernel is Linux (which is the most likely), you need to pass "init=/etc/bochs-init/init.sh" as a kernel parameter. Beware that Bochs is not particularly dessigned to be secure from local attacks. This will let any user with physical access to the system to run Bochs. Don't use this feature if you're concerned about local security. EtherBoot support ----------------- To be able to use EtherBoot within Bochs you can read the following info: The pseudo NIC is now enabled by default, so there is no need to rebuild the package. SeaBIOS ------- Bochs can boot with SeaBIOS, both as the main BIOS and as the VGA BIOS. With the seabios package installed, romimage: file=/usr/share/seabios/bios.bin will use the main BIOS from SeaBIOS, and vgaromimage: file=/usr/share/seabios/vgabios-cirrus.bin will use the Cirrus VGA BIOS from SeaBIOS. In a PCI setup, the latter needs a PCI VGA, for example vga: extension=cirrus and something like pci: enabled=1, chipset=i440fx, slot1=cirrus Because the PCI VGA adapters are combined PCI/ISA devices, they must be assigned a slot explicitly. The SeaBIOS Cirrus BIOS works with Bochs’ Cirrus adapter, and the SeaBIOS standard VGA BIOS (stdvga) works with Bochs’ PCI VGA adapter.
